"The lamps are going out all over Europe. We shall not see them lit again in our lifetime." So said British Foreign Secretary Sir Edward Gray on the eve of the Great War in 1914. The Bolsheviks seized power in Russia in 1917, and Spain was ripped by civil war in the 30s, while Japan invaded China and Mussolini invaded Abyssinia. This visual history is the first in a series chronicling wars of global significance, informed by period reports and eyewitness accounts and illustrated with hundreds of captioned photographs from the archives of London's Daily Mail, one of Britain's leading newspapers since the turn of the 20th century.
